Modifying the Parameters
PARAMETER NAVIGATION
The operating parameters, modifiable using the keypad, are divided
into two types: frequent (type F) and configuration (type C). Access
to the latter is protected by password (default= 22) to prevent
accidental or unauthorized modifications.
Accessing the type F parameters:
• press the SET button for more than 3 s (if there are active alarms,
mute the buzzer), the display shows the parameter code ‘PS’
(password);
• use the UP and DOWN buttons to scroll the parameters. The LED
corresponding to the category of parameters will be on;
• press SET to display the value associated with the parameter
increase or decrease the value using the UP or DOWN button
respectively;
• press SET to temporarily save the new value and display the
parameter again;
• repeat the procedure for any other parameters that need to be
modified;
• press the SET button for more than 3 s to permanently save the
parameters and exit the parameter setting procedure.
Accessing the type C parameters:
• press the SET button for more than 3 s (if there are active alarms,
mute the buzzer), the display shows the parameter code “PS”
(password);
• press the SET button to access the password setting;
• use the UP and DOWN buttons to scroll the numbers until
displaying “22” (password to access the parameters);
• press the SET button to confirm the password;
• use the UP and DOWN buttons to scroll the parameters. The LED
corresponding to the category of parameters will be on (see

parameters and exit the parameter setting procedure.
Warnings:
If no button is pressed for 60 s, all the changes made to
the parameters, temporarily saved in the RAM, will be
cancelled and the previous settings restored.
The dAY, hr, Min parameters are not restored, as these are
saved instantly when entered.
If power is disconnected from the instrument before
saving the settings (pressing the SET button for 3 s), all the
changes made to the parameters and temporarily saved
